Ca Smog is crazy nazi and they will check to make sure it is the right cat for the vehicle. Your best bet is to buy a new one. I think I paid like $380 installed a few years ago...
Did it fail smog? Or is it rattling, broken etc?
Right after I bought mine, I smashed it up on the rubicon. Honeycomb on inside is completely destroyed and you can hear it rattling.. Still passed smog.
Where did you buy your new one? And I gutted mine. I crushed mine on the rubicon and destroyed the honeycomb too. I smogged it like that and passed with 3ppm to spare lol. So then I shook everything out of it and now I'm looking at my options for when smog rolls around again.
Good call. An old buddy of mine works at a muffler shop owned by his dad that's not too far from my work. I'll hit him up and see what he can do for me.
I got mine from a muffler shop. It sucks to spend a few hundred on a cat. But its not too bad. My honda needed a cat right before I sold it.. $1400!! FML (but I didnt pay that, I have my ways)
I got mine from rockauto. I made sure it was the right one by comparing model numbers and making sure it was CA smog legal. I ended up getting the same exact one autozone sells for $100 cheaper.
